Don't know the personalities involved, but this smells to me like a case where the SEL onboard confused "handling it among ourselves" with "ignoring the problem". (e.g., "I talked to Smitty about what happened, he won't do it again.") Unless they're like every chiefs' mess I've ever known, there's no way the entire goat locker on a cruiser didn't know something was up with one of their own.
Zipper-control problems have brought down many an otherwise good leader. Won't be the last time. Where it gets out of hand and causes real damage to the command is when peers and superiors ignore the problem or try to make it disappear.
